PUNCHlNG-BAG.

SPECIFICATION forming part of Letters Patent No. 774,18 dated November 8, 1904.

Application filed April 30, 1904.

To all whom it may concern.-

Be it known that I, JOHN G. KEITH, a subject of the King of Great Britain and Ireland, residing at 246 Fulton street, borough of Brooklyn, in the county of Kings, city and State of New York, have invented new and useful Improvements in Punching-Bags, of which the following is a specification.

This invention relates to an improvement in punching-bag supports; and its object is the provision of a punching-bag support which is adjustable to diflerent heights.

A further objectis the provision of a punching-bag support which is adjustable to different heights, all the parts of said support being secured to a single plate which can be readily attached to or detached from a wall.

A further object of the invention is the provision of means for bracing the punching-bag support in any of its adjusted positions to give rigidity thereto.

A still further object is the provision of an improved clutch for securing the support in its adjusted position.

In the drawings accompanying this specification, wherein a preferable embodiment of my invention is shown and wherein like letters of reference refer to similar parts in the several views, Figure 1 is a perspective view of my improved punching-bag support secured to a wall. Fig. 2 is a side elevation of the same, and Figs. 3, 4, and 5 are detail'views of the clutch for locking the support in its adjusted positions.

Referring now more particularly to the drawings, A is a base-plate, which is adapted to be secured to the wall in any suitable manner. Secured to the upper and lower portions of the base-plate and extending substantially at right angles therefrom are the anglebrackets B B, in which are secured in any suitable manner the guide-rods C O.

D is a T-rail secured to the base-plate A between the brackets B B and directly behind the guide-rods O C.

The punching-bag support comprises the substantially horizontal arm E and the downwardly-extending arm E, rigidly secured to the outer end thereof in any suitable manner. To the inner end of the rod E is secured a Serial No. 205,744. (No model.)

ries a clutch-lever G and a lock L therefor for holding the support in various positions of adjustment on the guide-rods C O, as is clearly shown in Figs. 3 and 4. The downwardlyextending arm E of the support is made hollow to permit of the passage therethrough of the cord h, which supports the bag H, and the lower end of said arm is made bell-shaped, as at e, to prevent the cutting or chafing of the cord it against the edges thereof when the bag is struck. The upper end of the arm E of the support is provided with a tubular sleeve 0, through which the cord it passes,

said sleeve being provided with a cam-lever c or other suitable locking means to clamp the cord therein. It will thus be seen that by clamping the cord in the desired position in the sleeve the bag H can be caused to hang a greater or lesser distance from the open end 0 of the arm E, according as the user desires to cause the bag to swing in a large or small are.

I is a disk-shape striking-plate secured upon the arm E and against which the bag H contacts when struck. The striking-plate I is provided with a centrally-disposed aperture and with a sleeve a, secured to its upper side and forming a combination of said aperture, through which the arm E passes.

The sleeve 2' is provided with a set-screw a" or other suitable locking means, by means of which the striking-disk may be clamped in any desired position of adjustment on the arm E. Pivotally secured to opposite sides of the arm E of the support near its outer end are a pair of rods K K, the free ends of which are in a telescopic engagement with the hollow tubes K K, the outer ends of which are pivotally connected, in any suitable manner at points some distance apart, to the base-plate A. Secured in the free ends of the hollow tubes K K areset-screws 7c in, means of which the rods K K and tubes K K may be rigidly connected. It will be seen that the rods K K and the hollow tubes K K form braces which will hold the support rigid regardless of the position to which it is adjusted on the guide-rods C C.

1 will now describe the particular form of lock which 1 purpose using to hold the support in various positions of vertical adjustment.

(Jr is a clutch-lever provided at one end with a suitable handle g. The opposite end of the lever G is bent back upon itself to form the hook-like portion g. The lever Gr diminishes in thickness from the handle g to the hooked end g and also from its upper to its lower edges, the thickness of the lever at the hooked end being less than the width of the space between the bars C C and the thickness of the part of the lever adjacent the handle being greater than the width of said space. The hook-shaped end g of the lever projects through the'bars G C and is pivotally secured in any suitable manner to the rear side of the block F.

From the above-described construction it will be seen that when the handle g of the lever Gr is elevated the narrow portion or end of the lever will be drawn into the space between the bars C (J and the block F will be free to move thereon, and when the handle is dropped the lever G will fall, and owing to its peculiar shape the thickest portion thereof will come between the bars 0 C and exerting a wedge action thereon will lock the block F in position. In order to prevent the accidental dislodgment of the clutch-lever Gr, 1 have provided a lock L therefor to hold the same in its lowered position. The lock L comprises a plate mounted to slide transversely on the block F by means of a pin-and-slot connection therewith, said plate being kept from rocking by meanspf rearwardly-extending lugs Z, which underlie the lower edge of the block F. The plate L is provided with a depending portion Z, which when the plate is pushed as far as possible to the left is adapted to overlie the upper portion of the lever Ur and hold the same in its lowered position. The lower edge of the depending portion Z is preferably camshaped, so that when it is moved to overlie the lever Gr it will by contact with the upper edge thereof force the same down into engagement with the bars C (J. The lock L is gllsol provided with a suitable operating-han- Having described the construction of my device, I will now set forth the manner of using the same. The set-screws 7r; 7r: of the braces are first loosened. The clutch Gr is then loosened, and the arm E is then slid along the guide-rods G G to the desired position, and the clutch is operated to lock it in said position. The support having been secured in the desired position on the guide-rods C C, the set-screws M1: of the braces are then tightened. By means of the clamp e the bag H is adjusted to hang the desired distance from the end of the arm E,according to the arc in which the user desires it to swing, and the strikeplate I is then adjusted on the arm E, by means of the set-screw a", to such a position that the bag will contact therewith when struck.

1 do not desire to limit myself to the precise form of support shown in the drawings, as it is obvious that many minor changes might be made thereto without departing from the spirit of the invention.

Having thus described my invention. what I claim as new, and desire to secure by Letters Patent, is
